District partisanship

FairVote's Monopoly Politics 2012 study

In 2012, FairVote did a study on partisanship in the congressional districts, giving each a percentage ranking (D/R) based on the new 2012 maps and comparing that to the old 2010 maps. Kentucky's 3rd District saw no change in partisanship due to redistricting.[11]
